Some of the common questions we are asked about BASE Platform.

1. For which customers and markets are BASE products relevant?
There is quite a range of organizations from commercial and public sector that might be interested in bathymetry such as oil and gas industry to build pipelines and platforms and also for operations; you can think of shipping channels, renewable energy with a new market with wind farms, harbours and ports and governments that need to know information about bathymetry, amongst others. 

2. How do your results compare to traditional survey methods?
Comparing our product with multibeam surveys, basically we are not competing with the quality of the data that surveys can generate but not everybody needs that quality for their application. What we produce is significantly more cost effective than multibeam survey and we can cover a bigger area and depth range. 

3. When is the BASE service going to be available for customers’ evaluation?
We are having some use cases now at different trial areas but we will like to have some early adopters as well and we plan to open the platform around October 2017 so customers can evaluate some data for an area of their interest after October.  

4. Is there a discount price for early-adopters?
We have two types of products: off-the-shelf products which are available from the portal with immediate delivery and on-request product which is more customised depending on the user needs and the delivery would typically take a month or so. 
While we are still developing the project and our products if you are interested in a certain area we will be pleased to try it out and be accommodating on price. In the early days we are very interested in working with prospective users that help us with the development of requirements and develop a better product. 

5.  Is there a level of accuracy given with each dataset?
All the datasets have the metadata attached where you can find the accuracy, amongst other characteristics such as resolution or the satellite’s acquisition time, if applicable. 

6. How are the final products evaluated (accuracy and morphology)? And what are the best ways for users to evaluate the accuracy (despite in situ comparisons)?
During the data merging process where we use different forms of data merging algorithms, we also look at the discrepancies of the data and check them for consistency with statistics that the different sources provide.
Of course we would like everybody interested in our products to come up with their own comparison for areas where there is (partial) survey data available and getting some feedback from you about the quality of our products.

7. What are the possibilities of the different techniques (optical, SAR, etc) to also classify bottom types (i.e. rock versus sediment and even finer)? 
Optical satellite data can provide this information for shallow waters. Optical and SAR data can provide this information for tidal flat areas like the Wadden Sea. If you are interested to have this as additional product, let us know and we will be happy to discuss it.

8. Apart from the standard products, is it possible to provide customized products?
There are a number of options for customization. We will deliver the data through the portal in a number of formats and certain resolutions, etc. Those will standardize for use of production channel but if the user has different requirements in terms of projection, resolution, or a special request such as looking through older satellite data to obtain data in a particular difficult area, we can accommodate that with an offline request.. 
Custom options are possible, please get in touch and tell us your needs. Customization options may include, but are not limited to, special data formats, custom resolution, direct delivery, products created from satellite data collected at a particular date.

9. Is it possible to contribute to the project? With the contribution can I obtain discounts for the products?
If you are interested in discussing opportunities and possibilities to cooperate in the project or like to add your data to BASE-platform, please get in touch.

10. What is the added value of BASE products with respect to existent free data such as EMODnet or GEBCO? 
The data we are generating is high resolution and with detailed metadata information available. Also, it is mostly not older than 1 or 2 years, while the free databases often have not been updated in many areas. EMODnet also has many areas where only GEBCO data is available.  

11. What are the depths range and spatial resolution for each technique? 
With optical techniques you can cover shallow waters up to 30 m with a resolution from 2-15 m. SAR is for deeper waters with depths around 10-100 m and a spatial resolution of 500 m. For altimetry, the depth rage is more than 2000 m, with a restriction of 10 km from shore and the spatial resolution is 1 km. Crowd sourced bathymetry covers depths from about 1-2000 m with a resolution of 12 m. 

12. What kind of software are you using to acquire and process data in BASE-platform project? 
The data acquisition and processing workflow depends on state-of-the-art algorithms developed by the individual provider.

13. How often are data updated? 
Updates will be demand-driven by the user community. Data for areas that are not yet available in BASE will be created upon request and once created will be available off-the-shelf. Available source data will specify the acquisition time and you can decide to use it (for a discount) or request a new acquisition.

14. How long does it take to process an order from the platform? If today I would like to sign in the platform, what should I do? 
Please register for a beta account. Once you have logged in you will be able to download the trial data and get the first experience of the ordering process - and even request a quote.
Once we go live, off-the-shelf data should be pretty much orderable immediately. For offline orders we will need to we expect that process to be around one month or so but this needs to be confirmed. We need to contact the providers and keep you fully informed of the process of your order. 
It also depends on the source that is required. For crowd sourced bathymetry, if you are asking for an area where there is no information, it takes a significant period of time to talk with vessels and compile the information. For optical data it can be from few days to few months, depending on the size of the area, etc. In the case of altimetry it takes from two weeks to one month.
